For the first time researchers from both Sheba Medical Center and Tel Aviv University have grown human kidney organoids (a synthetic 3D organ culture) from tissue stem cells in the laboratory mirroring human fetal kidney development.
A new study by researchers at the Icahn School of Medicine at Mount Sinai finds that widely used AI chatbots are highly vulnerable to repeating and elaborating on false medical information, revealing a critical need for stronger safeguards before these tools can be trusted in health care. The researchers also demonstrated that a simple built-in warning prompt can meaningfully reduce that risk, offering a practical path forward as the technology rapidly evolves. Their findings were detailed in the August 2 online issue of Communications Medicine [https://doi.org/10.1038/s43856-025-01021-3].
Slow scintillation component due to charge carrier capture at point defects is a serious issue in scintillator materials. Therefore, the fabrication of scintillators with a high proportion of fast component in scintillation response is of great interest to material scientists. By applying the defect engineering strategy in the advanced optical Lu3Al5O12:Ce,Mg (LuAG:Ce,Mg) ceramics, ultrahigh fast scintillation proportion can be achieved with slight loss of the fast scintillation light. This strategy has a broad application potential in improving fast scintillation proportion of various oxide scintillators.
Scientists have developed a new cooling device that can significantly enhance electricity generation in solar power systems.
New molecular capsules capable of imparting chiral activity to non-chiral metal-containing dyes were successfully created by self-assembly in water, as reported by researchers from Japan. These capsules have adaptable chiral cavities, inducing chirality of various large and rigid metal-containing dyes upon encapsulation, without requiring typical chemical modification. Moreover, the chiral properties can be tuned with heat, showcasing the potential use in chiral materials and catalysts.
